Abstract

A 3D virtual simulation tailoring technology of clothes is a new tendency developed after three mature modules (pattern making, pattern grading and marker making) in a clothes CAD (Computer -Aided Design) system. When the 3D virtual simulation tailoring technology is used in a clothes field, time for designing new clothes can be shortened through the simulation of a manufacture process of sample clothes so as to greatly shorten a ready-to-wear production period. Meanwhile, the 3D virtual simulation technology provides a new path for a clothes selling way, and therefore, the popularization of online sales and an online new clothes presentation can become possible.

Description

A kind of 3D virtually simulation of garment ready-made clothes technology

Technical field

A kind of field about computing machine 3 D virtual analog technology.

Background technology

From the nineties in 20th century. many experts and mechanism start the three-dimensional simulation research of virtual costume, are two-dimensional analog and laid out flat before.Current research emphasis has two: one to be that the quick collision algorithm of exploitation is for clothes modeling; Another is " garment piece---sew up " system.The brand in domestic and international CAD/CAM system R&D firm with 3D garment virtual function has the 3 D stereo sample clothing system (system 3D sample) of Canadian PAD; The Fashion Design system (3D-Fashion Design System) of U.S. CDI (computer design incorporation); The Runway 3D of U.S. PGM; V-the stitcher (virtual stitching) of U.S. Gerber; The e-design of France Lectra; Hispanic i nvestronica system etc.

The 3D dressing system of PGM company of the U.S. reaches more than 95% to its really degree of the simulate effect of clothes. in the rag trade in Europe, there is good utilization rate.In recent years, PGM CAD/CAM system continue GERBER.PAD, LETRA etc. these after international and that China's impact is larger CAD of Garment/CAM R&D firm. by means of the operation interface of its close friend. practical system tool, with the CAD/CAM file of the intercommunication of other software in river, Zhejiang one is with and captured the larger market share.

Summary of the invention

Do not have to find the application materials about this system aspects by national patent retrieval.

The RUNWAY 3D garment virtual technology of PGM is placed on virtual human body by the garment piece that two dimensional surface designs by computing machine. sews up and generates three-dimensional clothes, belong to " garment piece---sew up " system.The process that he simulates ready-made clothes is divided into five steps:

The first step: three-dimensional body model;

The fitness of clothes, comfortableness carries out evaluation when wearing be the most accurately.3D model is set up to be the first step simulating ready-made clothes.Deviser can utilize the three-dimensional body model storehouse of body model's tool to open, and specifying model to wear Clothing Sample also can according to required human dimension instrument adjustment model size.Except can to the size of model's 40 main portions (as height. chest measurement, waistline, hip circumference. breastheight point etc.) regulate outside, also adjustable skin, face, hair and posture and figure etc.The size of national standard human body can input by we. and the three-dimensional body model in the side of hideing provided in amendment model storehouse sets up the model that wears the clothes needed for oneself. and amendment result can be preserved in order to using next time.

Second step: two-dimentional garment piece pattern controls;

By the model garment piece that designs through on body model, first need by each garment piece according to being worn in the upper residing position marshalling on two dimensional surface successively of body model, and each garment piece longitudinally to be placed by woven design direction.Then set the title of every sheet garment piece in garment piece control group, bend percent, the parameters such as geometric configuration according to the bag Girth-designing of garment piece to human body, finally according to the fabric of the selected garment piece of design.

3rd step: sew up;

Clothes is mutually sewed up by garment piece to form. in simulation ready-made clothes process, also need set suture on garment piece. and garment piece simulation could unite by a seam by computing machine.We use suture instrument on garment piece, set up suture one to one, such as: when anter and rear panel are sewed up. the rear panel that anter has suture corresponding also there is a suture.This process will very IIt, D, and all sutures can not lack, otherwise garment piece finally cannot become complete clothes.Also can freely control in simulation ready-made clothes process stitch (shrink. border. folding etc.) performs setting, then computing machine is placed on garment piece around the corresponding site of body model, automatic imitation stitching

4th step: try on;

Can start the instrument of trying on after setting needed on garment piece is complete, garment piece simulation is stitched into clothes, and be worn on virtual human body model, simulation the true of clothes wears effect.Simulation clothes can embody the texture of various fabric when wearing and textural effect, the flower pattern of fabric in natural reality ground. and pattern, color arbitrarily can be changed by deviser.Deviser also can according to its length growth rate of the property settings of different fabric. improve fitness when clothes are worn.

5th step: model correction;

Designer can use mouse all-directional rotation dressing model, directly observes effect and the details of each angle dress in each position of garment piece.Use tension figure in red, green. blue three-color can demonstrate the tightness of each position clothing body.According to the tension figure of dressing effect and reflection clothes different parts elasticity. deviser just can correctly correction molded dimension, and that improves clothes wears effect, the wearing comfort of raising clothes.

The application of current rag trade three-dimensional garment virtual technology lags far behind the industries such as film, animation, building.One, simulates flexible fabric technically, solves non-rigid human body and clothes Interaction Force easy thing by no means. and three-dimensional garment virtual technology need perfect.Its two, the network selling of clothes also needs significant progress, and three-dimensional garment virtual technology can't fully demonstrate the advantage with alternative traditional dress marketing method.Its three, three-dimensional garment virtual technology exploitation difficulty large. cost is high. promote have certain difficulty.Believe along with integrate figure, literary composition, sound, as network technology combine with 3D mono-Garment CAD system. the production of rag trade and supply and marketing mode are bound to produce deep change.
